SPECIFICATION forming par-t of Letters Patent No. 382,590, dated May 188g.

Application filed February 25, 1888. Serial No. 265,316. (No model.)

To all whom it may concern,.- u

Be it known that I, WILLIAM H. CLAY, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut,have invented certain new and useful Improvements lin Soldering Clamps; and I do hereby declare the following to be a 'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to produce a device of this class which shall be simple and inexpensive, practicallyimpossible to get out of repair, adapted to grasp any size of pipe withiny reasonable limits, and to be used in any of the various positions in which it may be required to wipe a joint, it being equally adapted for use in joining two straight pieces of pipe or in making T-joints, in the former/ instance two clamps being required and in the latter th ree.

With these ends in view I have devised the novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to denote the several parts.

Figure 1 is a side elevation; Fig. 2, an end elevation, and Fig. 3 a section corresponding with Fig. l. The several views illustrate the invention as applied to different sizes of pipes,

The holding device consists of a U-shaped piece of metal having a rod, 8, extending across its open side, and a thumb-screw, 9, which' passes vthrough the back of the U-shaped piece, the end of said screw being adapted to engage the back of one of the jaws. l y

The bifurcated standard 5 cbnsists of two separated side pieces projectin'g upward from the base 3, and between which are pivoted the jaws 6, said side pieces being rigidly connected near their upper ends by a cross bar l PATENT OFFICE.

or pin,10. The grasping portions of the jaws consist of two segmental pieces, 11, preferably lined with pieces of leather, 12. VThe backs of the jaws are provided with vnotches 13 to receive the cross-rod 8 and the point of the thumbscrew 9 of the holding device 7. v In practice as many clamps are required as 6o there are pipes to support, the screws being .j turned into a plank or box, which is so placed as to hold the clamps in the desired position. j

It of course frequently happensthat the 5 pipes are so located that the screws may be 65 "j turned into the wood-Work ot' the building. It will be apparent from the drawings that when the h'olding device is lowered the jaws will drop apart. Having placed the clamp in suitable position,the jaws are placed on opposite sides of the pipe tobe held and the' holding device lifted up as far as it Will go, cross rod 8 lying in a depression in the back of one of the jaws. Thumb-screw 9 is then tightened up, and of course engages the corresponding depression in the opposite jaw, as clearly shown in Figs. 1 and 3. This locks -the jaws in position and clamps them rmly about the pipe. It will be seen that the def j vice is self-adjusting to all ordinary sizesofo" P1130- l l To disengage a clamp from a pipe it issimply necessary to turn the thumbscrew backward until cross-rod 8 will slip out from the depressionin which it has been lying, which will permit the holding device to drop down.y To grasp a pipe the Ajaws are simply placed on opposite sides thereof, the holding device lifted up as far as it'will go, and the thumb-kr screw tightened up, as already fully described.'

I claimt A soldering-clamp consisting of the combi` nation of a base, 3, having a holding-'screw,4, a bifurcated standard, 5, consisting of twoseparated side pieces rigidly connected near their 95 i upper ends, two clamping-jaws, 6, provided` with notches 13 and grasping portions-11, and a holding device, 7, having cross-pin 8 and, thumb-screw 9, substantially as set forth. .j In testimony whereof I affix my signature in rco presence of two witnesses.
